Press fit analysis with enforced rotation

Recommended Posts

Hi,

 

I am currently doing press fit analysis of silent block bush using MATHE card. I am ready with mesh and contacts. I want to give rotation as load to specific node set and want to check how rubber bush behaves and how much stresses are generated. I have tried to create cylindrical coordinate system (R, Theta, z) and assigned that system using assign option in system panel to specific nodes and given rotation in degrees.  I checked in Hyper View and found it is moving in Y direction and not as per cylindrical coordinate (Theta direction). Please let me know where I am going wrong.

 

Regards,

Pratik

Hi Pratik,

 

Try this, add a layer of shell elements (or RBE2 elements) and apply rotational displacement around Y axis (DOF 5) and check the results.
